Ha Ha.. in how long! >Stop the Crap! Suppose that a tablebase takes 2 days to create today. Next year it will take one day to create it. The following year, it will take 12 hours. Year 3: 6 hours Year 4: 3 hours Year 5: 90 minutes Year 6: 45 minutes Year 7: 22.5 minutes Year 8: 11.25 minutes Year 9: 5.625 minutes Year 10: 2.8125 minutes Year 11: 1.40625 minutes Year 12: 42.1875 seconds Year 13: 21.09375 seconds Year 14: 10.546875 seconds Year 15: 5.2734375 seconds Year 16: 2.63671875 seconds Year 17: 1.318359375 seconds Year 18: 0.6591796875 of a second Year 19: 0.32958984375 of a second Year 20: 0.164794921875 of a second. What that means is that perfect information will be generated in a fraction of a second, if that is what is desired. This is a conservative estimate, since compute power seems to be growing superexponentially, rather than just exponentially.
